FIG. 7.1 The two simplest ring resonator configurations is a ring resonator shown in (a), giving a spectrum shown in (b), which looks like a notch filter response when the ring has finite loss. The power coupling coefficient |κ|² is 20% for critically coupled, 10% for coupled More about this image found in The two simplest ring resonator configurations is a ring resonator shown in...

of optical tweezer ( Ashkin et al., 1986 ) incoming spatially filtered laser beam focused using a microscope on a particle in a liquid. The focused beam undergoes reflections R₁ and R₂ and refraction by the sphere, resulting in a net upward force More about this image found in (a) Optomechanical crystal tightly confined mechanical and optical resonanc...
